Hi Linus,

Please pull this large pile of new xfs code for 5.9.  There are quite a
few changes in this release, the most notable of which is that we've
made inode flushing fully asynchronous, and we no longer block memory
reclaim on this.  Furthermore, we have fixed a long-standing bug in the
quota code where soft limit warnings and inode limits were never tracked
properly.  Moving further down the line, the reflink control loops have
been redesigned to behave more efficiently; and numerous small bugs have
been fixed (see below).  The xattr and quota code have been extensively
refactored in preparation for more new features coming down the line.
Finally, the behavior of DAX between ext4 and xfs has been stabilized,
which gets us a step closer to removing the experimental tag from that

We have a few new contributors this time around.  Welcome, all!

This branch merges cleanly with master as of a few minutes ago, so
please let me know if anything strange happens.  I anticipate a second
pull request next week for a few small bugfixes that have been trickling
in, but this is it for big changes.

  fs/xfs: Support that ioctl(SETXFLAGS/GETXFLAGS) can set/get inode DAX on XFS. (2020-07-28 20:28:20 -0700)

New code for 5.9:
- Fix some btree block pingponging problems when swapping extents
- Redesign the reflink copy loop so that we only run one remapping
  operation per transaction.  This helps us avoid running out of block
  reservation on highly deduped filesystems.
- Take the MMAPLOCK around filemap_map_pages.
- Make inode reclaim fully async so that we avoid stalling processes on
  flushing inodes to disk.
- Reduce inode cluster buffer RMW cycles by attaching the buffer to
  dirty inodes so we won't let go of the cluster buffer when we know
  we're going to need it soon.
- Add some more checks to the realtime bitmap file scrubber.
- Don't trip false lockdep warnings in fs freeze.
- Remove various redundant lines of code.
- Remove unnecessary calls to xfs_perag_{get,put}.
- Preserve I_VERSION state across remounts.
- Fix an unmount hang due to AIL going to sleep with a non-empty delwri
  buffer list.
- Fix an error in the inode allocation space reservation macro that
  caused regressions in generic/531.
- Fix a potential livelock when dquot flush fails because the dquot
  buffer is locked.
- Fix a miscalculation when reserving inode quota that could cause users
  to exceed a hardlimit.
- Refactor struct xfs_dquot to use native types for incore fields
  instead of abusing the ondisk struct for this purpose.  This will
  eventually enable proper y2038+ support, but for now it merely cleans
  up the quota function declarations.
- Actually increment the quota softlimit warning counter so that soft
  failures turn into hard(er) failures when they exceed the softlimit
  warning counter limits set by the administrator.
- Split incore dquot state flags into their own field and namespace, to
  avoid mixing them with quota type flags.
- Create a new quota type flags namespace so that we can make it obvious
  when a quota function takes a quota type (user, group, project) as an
- Rename the ondisk dquot flags field to type, as that more accurately
  represents what we store in it.
- Drop our bespoke memory allocation flags in favor of GFP_*.
- Rearrange the xattr functions so that we no longer mix metadata
  updates and transaction management (e.g. rolling complex transactions)
  in the same functions.  This work will prepare us for atomic xattr
  operations (itself a prerequisite for directory backrefs) in future
  release cycles.
